Was on a 16-hour road trip with my girlfriend this weekend. Saw nifty innovation on a stretch of I-80 in Indiana: deer detectors. They flash on the side of the road when one of the brutes is near, which seems to me a marvelous invention since one of the perils of leaving Manhattan is the possibility of having an a run-in with a deer, pretty much everywhere in otherwise-delightful red-state America.
